To all whom t may concern i i Be it known that I, WILLIAM Ri. HAMIL- TON, a citizen of the United States, residing at Dewey, in the county of Washington and State of Oklahoma, have `invented `certain new and useful Improvements in Turbine- Governing Mechanism, of which the follow-` ing is a specifica-tion.

This invention relates to an improvement in an apparatus for generating electricity, to be used for lighting purposes and the like, and the object is to provide means for rotating the generator for generating electricity.

A further object is in the provision of means for controlling the speed of rotation of the driving member.

The invention consists of certain novel features of construction and combinations of parts which will be hereinafter described and pointed out in the claims.

In the accompanying drawings Figure l is a view in top plan of the invention;

Fig. 2 is a view in side elevation;

Fig. 3 is a view in elevation of the driving member, showing the front plate removed;

Fig. 4L is an enlarged detail sectional view showing the valve and its operating mechanism; and

Fig. 5 is a perspective view showing the lever and its connections disassembled.

A, represents a shaft upon which is mounted the generator B and the mtor C.

A rotor 1 mounted on the shaft A, is provided with blades 2 on the periphery there of, and rotates within the casing 3. An inlet opening 4c is formed in the casing for the introduction of steam from any suitable source of supply, and leading from the opening are channels or passages 5. Leading from the channels or passages 5 are ports or ducts 6 and 7, for conducting the steam to the blades of the rotor. The port 6 extends downwardly, and the port 7 extends upwardly, so that the rotor will receive two impulses to each revolution, or in other words there is a constant pressure being exerted against the rotor at two opposite points for causing the rotor to be rotated.

, Needle valves 8 are slidably mounted in the casing 3, and extend through the ports 6 and 7 for controlling the admission of steam to the rotor. Brackets 9 are connected to the casing 3 and the other terminals of the valves 8 project through the brackets.

Springs 10 surround the Valves, one terminal of the springs bearing on the brackets, and the other terminal is engagedv by a nut 11 sore-wed upon each of the valves for normally forcing the valves outward to afford an unobstructed passage for the steam through the ports 6 and 7. An adjustable collar 12 is mounted on the needle valves 8 which is adapted to engage the brackets 9 for limiting the outward movement of the valves.

Crutch bolts 13 are adjustably connected to the casing 3 by means of nuts 14E, and mounted upon the ends of the bolts are heads 15. These heads are provided with a bifurcation 16 in which levers 17 are pivotally mounted. The crutch bolts are preferably made square at their free end, and the heads 15 have the bores thereof made square to lit over the squared ends of the bolts. Set screws 18 carried by the heads 15 are adapted to be screwed into engagement with the bolts for holding the heads at the proper elevation.

A governor consisting of a stationary block 19 is fastened to the shaft A, and a movable block 20 which is also mounted on the shaft. The two blocks are connected together by means of toggles 21. A spring 22 mounted on the shaft A has one end thereof in engagement with an adjustable collar 23 on the shaft A, and the other terminal in engagement with the movable block 20, for exerting a pressure against the movable block 20 to cause the toggle links to remain practically parallel with the shaft A.

An end of each lever 17 is connected to the movable block 20 of the governor, and the other terminal of each lever engages a valve 8.

When the shaft A begins to revolve at a speed which is too high for the purposes required the levers will be actuated by the movement of the block 2O moving toward the stationary block 19, causing the valves to be moved inward for closing the steam ports and thereby cutting oli' the steam to the rotor. This movement will generally be gradual, but the timing of the action of the levers on the valves is regulated by the adjustment of the crutch heads' 15 on the bolts 13.

I claim 1. The combination of a fluid pressure motor, a governor mounted on the shaft thereof, a pluralityV of spring actuated needle-valves in the sides of the motor,

crutchbolts connected to the motor, adjustable heads connected to the bolts, levers pivotally connected to the heads, a terminal of each lever connected to the governor, and

the'other terminal of each lever adapted to rality o-f spring actuated needle-valves inV the sides ofthe motor, levers connected to the governor extending in the path of Vthe valves, operated and controlled by theinovement ofthe governor for actuating the needle-valves, adjustable crutch -bolts to which the levers are fulcrumed, brackets connected to. the motor for guiding the valves, and adjustable collars connected to the valves adapted to engage the brackets for limiting the outward movement of the valves with relation to the adjustable fulcrumed levers.Y

3. The combination of afluid pressure motor, a governor on the shaft thereof, a plu- Copiesofths, patent` may be obtained for vefcents each, by addressing the Commissioner of Patents,
